18 to 60VDC Input Qtr-Bricks reduce inventory requirements
Power-One has introduced its QMS Series of 1/4-brick dc-dc converters. Three new single-output models provide 3.3VDC @ 25A, 5VDC @ 14A, and 12VDC @ 6.75A. Ultra-wide 18 to 60VDC input range facilitates operation from 24V and 48V; eliminating the need for multiple host-system circuit-pack designs, and reducing the number of brick part numbers in inventory, in applications such as wireless base stations.
Fast and Highly Integrated Four Channel Digital Isolators
Silicon Labs used todays Applied Power Electronics Conference (APEC) to announce the expansion of its digital power product portfolio. The Si844x is said to be the industry’s highest performance, easiest-to-use, lowest cost 2500VRMS digital isolator product family.
High Efficiency Transformers for PoE Applications available Off-the-Shelf
Focus EDL announces a series of high efficiency, small footprint, off-the-shelf power transformers for powered device (PD) side Power over Ethernet (PoE) products that meet IEEE standard 802.3af. Produced by Pulse, the parts are approved for use with many of the most popular PoE ICs and are available in standard output voltages from 3.3V to 12V
Power-One’s Z-One Digital IBA Powers “Triple Play” for Meriton Networks Optical Switching Platform
Power-One has released details about another Z-OneTM Digital IBA design win. Meriton Networks’ application is an optical switching platform for metro-area networks, that supports a range of data rates from 100Mbps to 10Gbps.
Wall-Mount Rectifiers provide up to 550W
UNIPOWER Europe has added to its Sigma Series with the introduction of a family of six wall-mount rectifiers designed as a quick and easy solution for powering a wide variety of telecoms equipment.
Flexible Inverter Satisfies Wide Range of Applications
The Quasar Inverter from Gresham Power will find a wide variety of uses over and above supplying high quality AC power from a DC source.
Integrated RGB controllers simplify design of diode sequencing for portable systems
To generate the three colours in an RGB LED, designers would typically need to use three separate MOSFETs, all the associated interface circuitry, and three GPIO pins on the system processor to drive the RGB LED. With AnalogicTech’s AAT4295 and AAT4297, designers can now support up to two RGB LEDs while eliminating the need for discrete MOSFETs and save the GPIO lines for other system functions.
75W ATX compatible power supply on PC/104 architecture
Providing up to 75W output capability with an integrated UPS and battery charger for NiMH and SVLA batteries, the new Micronix PV-5127S from Datasound Laboratories is said to be the first ATX compatible power supply on PC/104 architecture.
Tiny video driver removes GSM interference
A highly integrated, single supply video driver from Intersil has an 8 MHz low-pass filter that removes GSM noise from the video band, and also serves as an anti-aliasing filter. The ISL59111 also provides the added benefit of seeing input signals below ground.
Power supply charger combination is ideal for remote telemetry systems
Omniflex has introduced what it believes will solve voltage incompatibility problems in remote telemetry applications. The PT L50C-D is a combined power supply and dual charger that runs from a universal 85 to 264V AC input and is designed specifically for those applications that need to maintain both 12 and 24V systems.
